[PATCH 04/11] treewide: Convert struct kernel_param_ops initializers to DEFINE_KERNEL_PARAM_OPS

[Kees Cook <kees@kernel.org>]

Using Coccinelle, rewrite every struct kernel_param_ops initializer that
sets .get into a DEFINE_KERNEL_PARAM_OPS-family macro invocation,
for example:

@@
declarer name DEFINE_KERNEL_PARAM_OPS;
identifier OPS;
expression SET, GET;
@@
- const struct kernel_param_ops OPS = {
-       .set = SET,
-       .get = GET,
- };
+ DEFINE_KERNEL_PARAM_OPS(OPS, SET, GET);

Using the macro for initialization means future changes can manipulate
the struct layout and callback prototypes without having to change every
initializer.
